Furgil is the one to inform Psaro and Roseof the Maulosseum, upon the former winning Category F of the Endor Tournament in Terrestria. Posing as a talent scout for the Monster Mauling Association, the facetious feline entices the half-human by saying the Maulosseum poses a grander, more fulfilling challenge than anything in Terrestria and presents to him a piece of red travelite and informs him that an elf can make use of it to enter Nadiria.
Once Rose completes the ceremonial dance to activate the travelite, the entirety of Rosehill Tower is transported into the Lower Echelon of the Circle of Conquest with Furgil welcoming the duo. After explaining the nature of Nadiria and how it is divided into six circles composed of three echelons, he points Psaro in the direction of the Maulosseum and bids him a good journey. Once Psaro and Rose arrive, Furgil advizes that the monsters of Nadiria won't join just any old Monster Wrangler―Psaro will need to develop a reputation before they'll even consider joining him. For this echelon of the Circle of Conquest specifically, he must win in Category G to make an impression. Victory will also net Psaro a piece of yellow travelite, granting the pair access to the Lower Echelon of the Circle of Temper as well as words of congratulation from Furgil. Ominously, a spectra projection of Aamon watches Psaro and Rose as they leave the arena lobby, cackling that the Prince is wandering down the path he laid for him.
The remaining seven categories of the Maulosseum are entirely optional, though great rewards are given to the victor. Additionally Randolfo the Tyrant will attend the Category E tournament, leading to a unique cutscene.
